I think a reload without saving the app isn't possible with a command-line batch but you are a lot more flexible if you used vbs-batches, see here two examples: Reduce Number of Applications at a time.

You therefore need to implement a code in your "onpostreload" to do this

Using /v with a variable, you can have something to test in your code to determine whether or not you want the qv instance to quit, or if the document is being reloaded using the usual /r (and therefore does not need your code to close)
